A new family of chiral diamide ligands has been designed and synthesised. These ligands have been successfully applied to an asymmetric allylic substitution reaction. A palladium complex of one of the diamide ligands achieved enantioselectivities of up to 93% in the allylic alkylation of 1,3-diphenyl-3-acetoxyprop-1-ene.
